This disaster flick takes place in a small-small town where few people are seen while untold millions are killed off-screen via hearsay (New York, Boston, and Washington DC). Of the already miniscule cast, few survive. The scenes jump rapidly from enclave to enclave dealing with a barebones assessment of family dynamics, 2 bickering scientists with a single clue, and the suspect friendships among a tiny group of teens stuck in detention. The man in charge of these teens, including his son, proves an unerring lack of good judgment as the movie progresses. As with most movies like this, science terms are bandied about like they're going to mean anything to those of us who are just looking for action, suspense, and yes, a lot of crazy destruction (it doesn't qualify as a disaster flick if something doesn't get destroyed). In this case, buildings are reduced to nothing in the blink of an eye, people too. But it's not nearly enough devastation to justify their chatter about worldwide obliteration. (Truthfully, when they started yapping about some `destruction particle' and some foo-ton or was that futon, phooey-ton-ton-tooey-something........... I began to lose interest.) At least it rushed the plot along at a goodly pace, enough so you don't notice the obvious improbabilities like a plane crashing at a convenient location so the detention dad (David Sutcliffe) can just happen to be in the area at the perfect moment to move the plot along to the next obvious point (it felt less like a plot and more like a check list at that juncture). Still, there's enough goofy charm amongst the small cast to make things interesting. I liked it. I'd watch it again someday. I just don't want to have to feel like I need to study up on Jupiter in order to get what's going on.
